BUILDING BLOCK AND WALL.

SPECIFICATION forming part of Letters Patent No. 749,796, dated January 19, 1904.

Application filed April 13, 1903. Serial No. 152,362. (No model.) i

To all whom it may concern:

Be it known that I, FRANK E. KIDDER, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado,have invented certain new and useful Improvements in Building Blocks and Walls; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

.to the letters of reference marked thereon,

which form a part of this specification.

My invention relates to improvements in building blocks and walls formed therefrom, my object being to provide a wall of this class which shall be substantial and durable and produced at a minimum cost; and to this end the invention consists of the features, arrangements, and combinations hereinafter'described and claimed, all of'which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figures 1 and 2 show in perspective two forms of block from which the walls shown in Figs. 3 and 4 are constructed.

The same reference characters indicate the same parts in all the views.

Let A designate the block shown in Fig. 1 and B the block shown in Fig. 2. The block A is composed of a body part A and projections A extending from the blocks at right angles and located between its extremities, the said projections being suitably separated or spaced and of equal length. The projections A are also of the same height as the body of the block.

The block B is composed of a body part B, two right-angled projections B at its extremities, and an intermediate projection B equidistant from the end projections B The inner surface of the projection B is provided with a groove B to facilitate the holding of the blocks together when set in-mortar. The promg intermediately arranged or interlocked,

the vertical faces of the projections of each block engaging or abutting against the inner vertical surface of the other block, and the blocks which are on one side of one course or layer are on the opposite sides in the course or layer next above, thus alternating from side to side inthe vertical courses. (See Fig. 3.) The blocks are also. arranged to break joints in the Wall, or so that each block on one side of the wall overlaps the joint formed by the ends of the twovblocks on the opposite side.

In the construction shown in Fig. i, the arrangement is similar to that shown in Fig. 3,

except that the blocks in the lower course on opposite sides of the wall do not break joints.

Attention is called to the fact that the intermediate projection B of the blocks B is thicker, preferably twice the thickness of the end projections of the same block. The bond through the wall is obtained by the projections of the block of the same pattern overlapping each other in alternate courses.

.auiwm mj Having thus described my invention, what I claim is A wall composed of building-blocks A and B having right angled projections as described, the two sets of blocks being arranged on opposite sides of the wall so that their projections interlock and break joints, the two sets of blocks alternating from side to side in the vertical courses.

In testimony whereof I afiix my signature in presence of two witnesses.

FRANK E. KIDDER.
